Figure 1: Composite layered heater from patent US 9,224,626 B2 Alexander Glew, Ph.D., P.E. recently contributed to a new patent on an advanced thin-film electric heaters, layered composite heaters, for CVD semiconductor processing and related technologies titled “Composite substrate for layered heaters”. Watlow Electric, based in St. Louis, hired Glew Engineering and Dr. Glew to help develop this heater technology due to his experience in the Silicon Valley’s semiconductor industry. As a semiconductor equipment expert and materials engineering consultant, Dr. Glew’s familiarity with semiconductor manufacturing meant he understood both the limitations of common [...]
Conduction and Radiation of Thermal Energy In my last blog post, I wrote about the conduction and radiation of thermal energy through windows and the thermal transmittance value, called the U-Factor, that characterizes that heat transfer. The U-factor is useful in evaluating window performance and making wise decisions when specifying components for a building, but it is only one piece of the puzzle. The National Fenestration Research Council (NFRC) mandates a second value alongside U-factor in its certification process, called the Solar Heat Gain Coefficient (SHGC). SHGC [...]

Figure 1: Leonardo da Vinci, by Francesco Melzi Over the course of this blog series, I have written about a number of Italian Masters of science and engineering, from astronomers like Galileo and Cassini to physicists like Torricelli and Venturi. I’ve saved the best for last, however: Leonardo da Vinci. He is the quintessential renaissance man who fits both our running definition of “Italian Master” as well as being included in the standard list of Masters with Rafael, Donatello and Michelangelo Leonardo’s incredibly broad array of talents and interests have long been the subjects [...]
Portrait of Galileo Galilei Justus Sustermans [Public domain], via Wikimedia Commons I’d like to return to our previous series on the Italian Masters, focused not on the usual masters or painting and sculpture but on the masters or science, mathematics, and engineering. So far in the series I’ve written about the accomplishments of Volta, Cassini, Venturi and Torricelli. Today, I’d like to look at one of the greats: Galileo Galilei. Galileo is most famous today for standing up for heliocentrism against the Catholic Church and spending the last [...]
